spam phishing link

Yikes. I clicked on a "quickbooks invoice link" from an online vendor- it was taking a while and looked suspicious so I closed the window on my iPhone.

About an hour later, I got a legit email from the vendor, saying his server was hacked and that the 'quickbooks invoice link' that was emailed out was bogus, and to delete the email.

Which I did.

Should I be worried? is there anything else I should do for/with my iPhone to protect stored info?

Thanks in advance!
